Understanding Malware-Related File Loss
When malware infects your computer, it can wreak havoc on your system, including deleting important files. The good news is that in many cases, these files can be recovered through various methods and tools. This comprehensive guide will walk you through the process of recovering files deleted by malware and help you prevent future data loss.
Immediate Steps After Discovering Malware-Deleted Files
Before attempting any recovery process, it’s crucial to follow these essential steps:
- Stop using the affected drive immediately to prevent overwriting deleted files
- Run a full system scan with updated antivirus software
- Remove all detected malware from your system
- Disconnect from the internet to prevent further damage
- Prepare a separate storage device for recovered files
Methods to Recover Malware-Deleted Files
1. Using Windows File Recovery Tools
Windows offers built-in recovery options that might help retrieve your deleted files:
- Check the Recycle Bin first
- Use Windows File Recovery (available in Windows 10 and later versions)
- Restore previous versions through File History if enabled
- Access System Restore points if available
2. Professional Data Recovery Software
When built-in tools aren’t sufficient, professional recovery software can help:

- Recover files from formatted or corrupted drives
- Support multiple file formats and storage devices
- Provide preview options before recovery
3. Shadow Copy Recovery
Volume Shadow Copy Service (VSS) can be a valuable resource:
- Access previous versions of files through Properties menu
- Restore entire folders to earlier states
- Use third-party tools to access shadow copies
